CARLISLE, UK — CTC Marine Projects, a member of the Trico Marine Group, has been awarded its first contract in the offshore wind farm industry by E.ON Climate and Renewables UK. The contract is for the lay, installation and burial of 17 subsea power cable arrays linking wind turbine foundations at the Robin Rigg Offshore Wind Farm in the Solway Firth.
The Robin Rigg development consists of 60 wind turbines supplying power via two export cables. The CTC work scope will involve around 90 days of operation in shallow water depths of up to nine meters (29 ft). CTC will initially mobilize the aquatic reel drive system and tensioner spread on board vessel M/V Union Beaver for an anticipated 65 days duration. Once in the field they will perform the lay and installation of 98-mm (3.8-inch) and 113-mm (4.4-inch) diameter array cables followed by post installation inspection and testing.
Following the installation, the lay spread will be de-mobilized and remotely operated vehicle CMROV4 will be mobilized on board Union Beaver where it will perform the trenching of all the previously laid array cables.
CTC said it would be operating in very challenging conditions due to the tides, strong currents and unpredictable weather in the area making operations particularly complex.
Undertaking the first offshore wind farm job will also pose different safety issues for CTC, which the company said it was “confident in handling due to their stringent safety measures taken on all subsea projects.”
